New research from the Journal of Physiology suggests that impotence drugs like Viagra have more than just physical effects on men. They may also boost levels of a hormone associated with feelings of love. It was recently discovered that sildenafil, as Viagra is generically known, affects the part of the brain that controls release of oxytocin, a hormone associated with social bonding. And here we thought Viagra was supposed to cure softies, not create them! But wait, it gets better: Oxytocin is also the hormone that's involved in childbirth and nursing. But since discovering that Viagra and similar drugs can enhance feelings of affection in the brain as well as genitals, the professionals are getting worried. Wisconsin physiology professor Meyer Jackson, author of the research report, is like a mind reader or something, as he's able to predict how the wheels in our over-sexed minds are turning: "I hope that this doesn't cause some wild orgy of inappropriate recreational use."
